I don't know about the "Boca Bearings"...It says right in their header, "miniture bearings for the HOBBY market"....

Don't run them on my car but on my Promod bike I run the Worldwide brearings on the tranny,crank and wheels... they're darn near indestructable. You won't believe how long a wheel will turn if you spin it by hand, there's almost no resistance. Worldwide is great to deal with but the bearings are pricey and unless you're racing a pro class for big bucks they probably aren't worth it. I doubt you would gain a tenth, it's just something you use in a max effort vehicle when 'every little bit helps'.

i was thinking more long the lines of never having to replace a bearing again...

I don't know about 'never' but it would be a long time before you would need one. Like I said, almost indestructable....almost. The guy with the fastest blown,injected nitro T/F bike [5.82@249] uses them all over his bike including the crank and has for years with ZERO failures. Call Worldwide, they'll answer your questions, he's a great guy. It's been a couple a years since I spoke with him, I think Dave owns/runs the company.
